Solution for conflict between 3D virtual character of touch screen terminal and movement of scene vidicon

Abstract

The invention relates to a solution for a conflict between a 3D virtual character of a touch screen terminal and movement of a scene vidicon. The solution specifically comprises the steps as follows: 1, the movement direction of the virtual character is the direction of a gesture acquired in real time with respect to a virtual button coordinate system; 2, the position of the scene vidicon always stills at a fixed distance to a Z-axis coordinate of the virtual character, and moves along with the virtual character, and the direction of the scene vidicon always keeps equal distance and same direction with the virtual character, or keeps facing a screen; and 3, movements of the scene vidicon and the virtual character can be computed in a same progress, computation is divided into four kinds of computation according to different gestures in a horizontal direction, and the vertical computation is separately computed according to a gravity rule. According to the method provided by the invention, the virtual button is combined with the gesture, computation of a trigonometric function is avoided, and the problem of the conflict between the character and viewing angle control is solved by horizontal coordinate conversion of the screen.

Description

technical field [0001] The invention relates to the field of virtual games, in particular to a method for solving the motion conflict between a touch-screen terminal 3D virtual character and a scene camera. Background technique [0002] The control of the virtual character is divided into three types: posture control, motion control and perspective (also known as viewpoint) control. The angle of view control is to solve the problem of consistency between the angle of view of the character and the virtual scene. In practical applications, this problem is a common and difficult problem to solve. And the emergence of touch-screen mobile terminals makes the traditional keyboard and mouse control methods no longer applicable. It is necessary to re-study the operation set that can adapt to the new situation in order to realize the control of virtual characters. There are two existing perspective control technologies: one is to divide the world coordinates into subspaces of the s...

AI Technical Summary

Problems solved by technology

However, the natural person turns at any angle, so high-fidelity simulation cannot be performed, and the scale is too large and the calculation accuracy is low, which can no longer meet the needs of users

[0004] 2. The trigonometric function method has high precision and good fidelity, but the control effect is poor, the calculation time is too long and it is easy to cause system crashes and other problems

Since the computing power of touch-screen mobile devices is far from comparable to that of PCs, this solution is rarely used in practical applications.

[0005] 3. On the touch-screen mobile terminal, the control mode of the 3D virtual character cannot be carried out by using the traditional keyboard and mouse control method, and a new control mode must be adopted to solve the control problem of the virtual character. Commonly there are two kinds of virtual button and gesture control; Among them, the virtual button is a virtual object in the form of a button fixed at the front of the virtual scene

Simply use gesture control, the same as the subspace method, the character's steering range is limited
